True, if you are trying to emulate an entire cluster of servers on your laptop you are in for a bad time.
I’ve done that! But I also have 32GB RAM in my machine :) I want 64 GB but I will say for my current needs, 32 GB is the sweet spot. My normal daily use is around 20GB. And it is a MacBook Pro. One day I’ll probably go back to a laptop running Linux. It is the fastest for code compilation in my experience.
But it's not just memory, I find running code on MacOS generates a lot more heat causing the CPU to spike and harder to run in the first place.
